How RFS Biofuel Mandates Drive Imports
It should come as a surprise to congressional supporters of the Energy Independence and Security Act (EISA), that their 2007 votes to expand the Renewable Fuel Standard (RFS) to advance “homegrown energy” would lead to historic U.S. imports of biodiesel. Here’s a look at how exactly that’s happening: Though the conventional requirement can be met with various biofuels, ...

Petition for Waiver of 2016 cellulosic biofuel volumetric requirements
On December 28, 2016, the American Fuel & Petrochemical Manufacturers (AFPM) submitted a petition requesting that EPA waive the cellulosic biofuel volumetric requirements for the 2016 compliance year citing an inadequate domestic supply of the fuel. Based on the amount of cellulosic fuel produced through November, AFPM estimated that between 173.8 and 190 million gallons will be produced in ...

Unconventional Pretreatment of Lignocellulose with Low-Temperature Plasma
Abstract Lignocellulose represents a potential supply of sustainable feedstock for the production of biofuels and chemicals. There is, however, an important cost and efficiency challenge associated with the conversion of such lignocellulosics. Because its structure is complex and not prone to undergo chemical reactions very easily, chemical and mechanical pretreatments are usually necessary to be ...

How is Ethanol Produced?
What is ethanol? Ethanol is an alternative fuel made from corn, sugarcane, wheat, and other agricultural products, and is produced by the fermentation of carbohydrates such as sugar, starch, and cellulose. Ethanol Feedstocks All plants contain sugars that can be fermented to make ethanol in a process called biochemical conversion. Plant material can also be converted to ethanol using heat and ...

EPA Close To Publicizing 2017 And 2018 Renewable Fuel Standard Volumes
On April 15, 2016, the U.S. Environmental Protection Agency (EPA) sent its newly proposed Renewable Fuel Standard (RFS) volumes for 2017 and 2018 to the U.S. Office of Management and Budget (OMB) for review. Under the Clean Air Act (CAA), EPA must set standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel by November 30 of the year before the standard ...

Effect of solid-state NaOH pretreatment on methane production from thermophilic semi-dry anaerobic digestion of rose stalk
The effects of solid-state NaOH pretreatment on the efficiency of methane production from semi-dry anaerobic digestion of rose (Rosa rugosa) stalk were investigated at various NaOH loadings (0, 1, 2, and 4% (w/w)). Methane production, process stability and energy balance were analyzed. Results showed that solid-state NaOH pretreatment significantly improved biogas and methane yields of 30-day ...

Thermochemical pretreatment of lignocellulose residues: assessment of the effect on operational conditions and their interactions on the characteristics of leachable fraction
Annually, large amounts of agricultural residues are produced in Chile, which can be turned into a good opportunity to diversify the energy matrix. These residues have a slow hydrolysis stage during anaerobic digestion; therefore, the application of a pretreatment seems to be an alternative to improve the process. This work focused on applying a thermochemical pretreatment with NaOH on two ...

Lignin: A Possible Substitute for Petrochemicals in Products - Videos
Usually burnt to heat the facilities at pulp and paper-making operations after valuable carbohydrate components such as cellulose have been separated from the woody feedstock—and sometimes cursed for its tendency to stick like glue to the other components of the wood—the polymer lignin, making up almost a third of the wood in trees, has become hot property in research and development ...

Optimisation of pressed pericarp fibre delignification for glucose recovery using response surface methodology
In this study, pressed pericarp fibres (PPFs) were subjected to chemical pretreatment for bioconversion of lignocellulosic biomass to fermentable sugars. The effectiveness and comparison between pretreatments using acid (HCl) and alkaline (NaOH) to reduce the lignin content was studied. Alkali pretreatment showed better lignin removal than acid pretreatment. Subsequent experiments were then ...
